Problem

Description Hello, thank you for your work. I want to compile Sofa.

Steps to reproduce I did all installation steps https://www.sofa-framework.org/community/doc/getting-started/build/linux/ make the same structure as described & clone git clone -b v21.12 https://github.com/sofa-framework/sofa.git sofa/src. After configure cmake gui I got error:

-- Precompiled headers: disabled (SOFA_BUILD_WITH_PCH_ENABLED is OFF or CMake < 3.16).
Install prefix: /media/maxim/big-500/sofa/build/v21.12/install
CMake Deprecation Warning at SofaKernel/modules/Sofa.Config/CMakeLists.txt:80 (message):
  Deprecated components are activated (SOFA_WITH_DEPRECATED_COMPONENTS
  variable is ON)


Using legacy headers is enabled.
Headers from v21.06 are usable, but it is advised to change your code to use the new headers introduced in v21.12.

if(NOT cxxopts_POPULATED)
